PLASTER-SUPPORT FOR WALL-COVERING.

Specification of Letters Patent.

Patented Sept. 19, 1911.

Application filed July 15, 1910. Serial No. 572,088.

that class of devices and materials used forv f'- attachment to the studding of a wall or ceiling beams'as a means for supporting a plaster body or coating, the support being intended as a substitute for lath. A "common means is to produce sheets of material of'combined and alternating layers of paper and plaster which are attached to the wall and plastered over, and paper and other fabrics have also been used lnstead of lath,

the paper and other material being attached to the studding as plaster board. There 1s` a great advantage 1n using paper either in sheets or rolls or of a laminated structure, because of the fact that it can be readily handled, attached, and shipped, and because of the further fact that itis cheap; but a serious difficulty arises from the fact that the plaster is of necessity applied wet, and when it is applied to the paper in this condition the paper becomes saturated and weakened, and so sa s and sometimes breaks before the plaster ody becomes set, and where it sags seriously, the resulting wall is of course distorted and unsightly. I have found, howeverthat I can take suitable paper having a surface adapted to receive a plaster layer or coating, and use the aper either perforated or unperforated, ut preferably perforated,4 and stiften the paper by ap lying numerous transverse lily of metal to it, so that when these strips are attached to the studding or ceiling beams they will' etl'ectually prevent the paper and the att-ached plaster from saggingpr breaking away, and still extending asthey 4do transversely of the paperstrip, theyyvill permit the latter to be rolled like ordinary paper. In carr ing out this idea I refer to use a laminate paper, and the sti enin strips can be attached 1n such a Way that t e act of fastening the stifening strips to the paper will serve to fasten the laminas or sheets together, while they also stifen the whole and make it easier to handle without tearing the paper.

This will be better understood from the description which follows.

Reference is to be had to the accompanying drawings forming a part of this speciication, in which similar reference characters indicate corresponding parts in alll the views.

Figure 1 is a perspective view of a sheet of fabric, preferably paper of a suitable kind, provided with my improved stiifening means. Fig. 2 is a cross section ofV a wall provided with my plaster support and with a layer of plaster attached. Fig. 3 is a cross section of a wall showing how the adjoining sheets overlap when attached. Fig. 4 is an enlarged detail sectional view showing a preferred means of attaching a stifl'ening strip to the paper, and Fig. 5' is a broken face view of a wall with the plaster broken away, and showing the manner in which the aper or fibrous plaster support is applies.

The strip 1() of paper or fibrous material, but preferably paper, is long enough so that it can be rolled up as 'shown in Fig. 1, for convenience in shipping and applying, and it may be in a single sheet or laminated, and it is also preferably provided with peiforations 1l so that the plaster can .pass through the perforations and clench as shown in Fig. 2, but if the paper is of a reasonably loose texture the plaster, adheres to it perfectly, even though it is not perforated. I prefer to make the paper sheet of several lamin 12, as shown in Figs. 2 and 4, and these are held together by any suitable cement which will not be too hard but will be of a flexible nature so as to permit the paper to roll readily. Ordinary coal tar pitch is suitable for this purpose. The paper which serves as the wall support is attached to the studding 13 of a wall, and as above remarked, if it were unsupported, it would sag and sometimes break under the weight of the wet plaster which is attached to it, and to obviate this I provide numerous strengthening strips 14 which can be of any approved material but which are preferably thin sheet metal such as steel or iron, and these'are securely fastened to the paper preferably on the side which comes next to the plaster, though the stri s can be attached to either side or lic withinthe paper sheet, if desired. I do not limit myself to any particular means of i fastening the strengthening strips to the readilyl rolled.

7 shown the fastening" means serves to` paper, but Ifprefer 'to use thin fiat strips as shown, and these can be died out aS.

.shown at 1.5 so asto form struck-up brads 16 which are forced throughthe paper'layersand clenched, as clearly shown in Fig.

tachment, yet I do not limit myself to any Shape or to any fastening means, but as strengthen the cement by which the layers are secured together, and holds them so tha-t they'- cannot very Well be separated.

-When the Wall support is applied tothe studding 13, the sheets 10 are laid parallel with the studding and are made preferably in such Widths that one sheet'will extendacross the distance of two studs and overlap the next adjacent sheet, though obviously they'ca-n be made in vvarious widths. When attached thestrips 14 are arranged transverselyof the 'studsl and with the adjacent edges of the strips overlapping, as

d 5. The fastenthe studdingl. It will be seen, therefore, that it is not the mere stiffening of the paper which results from the .attachment of the strengthening ribs 14, but that v'vhen the support is applied to the studding and thenails driven through the soft materiahthe latter Will have to be stretched before it will break,

and so the paper is stiened according to the tensile strength of the strengthening ribs for strips, as the said strips are held taut and must either break orpullout the nails before lpermitting the plaster support to sag.

The plaster is applied asfusual in a layer l 1.7 so that it will pass "through the perforations of the paper and cover the-strips 14,

but in the use of the Word paper I wish it understood that I refer to any analogous lfibrous material of' a paper-like character.

, From the foregoing description it will be clearlyseen that I have produced a flexible easily handled cheapmaterial which can be readily attached to the studdingof a 'wall or ceiling beams, and which when so attachedforms' a secure support for plaster y l and is not likely to be Warped or distorted under the weight of the wet plaster. It will that While I have shown .thepreferred form of strip and means of at further be seen that the material Which I use is entirely flexible so that it can be handled and applied much better than the stiff sheets often used for the purpose. Attention is also called to the fact that material for Wall coverings is shippedin large quantities, and that thefreight item is a large one. But my improved covering is so flexible that it can be rolled in to a tight compact roll, and cheaply' shipped and easily handled. I Wish Vvto call attention to the further fact that the thin metallicy strips 14 lie flat and snug on the, paper, thus presenting a smooth, flat surface, and the plasterer can thus easily apply the plaster t'o the supporting paper and less plaster is required than on many materials which present rough or bulky exterior surfaces, which must necessarily be covered by the plaster. I claim l; A support-for Wall plaster comprising paper board of such fiexibility as to be com? pactly rolled and of such Width asv to span the stud spacing 'of a wall and spaced thin,

flat. strengthening strips extending transversely of and applied 'to one surface of the board and through fasteners engaging the surface of the said board opposite the ysaid strips, saidfasteners being connected to the strlp's.. 2. A flexible paper wall support for plaster comprising a board capable of being compactly rolled 'and of a widthequal tothe .said spacin of a Wall or multiple thereof,

and thin, at strengthening strips spaced I apart and extending transversely ofwthe 'l boardv and fasteners integral with the strips extending through and clenching on the side of the board opposite that engaged by said strips. V

3.` A support for wall plaster comprising a laminated sheet of fibrous material, and thin flat strengthening strips extendingV across the sheet, said strips having fastening devices integral thereon and extending through the laminas.

4.- A support for wall plaster comprising a I sheet of laminated paper board providing a plaster' hold suiciently thin to be capable A of being rolled and in width equal-to the stud spacing of a wall or a multiple thereof and spaced thin flat transverse vstrengthening strips applied to one surface and secured by through surface of said paper board.
